you could use event_generate() and bind_class(), as in this example:

from Tkinter import *
root = Tk()

def on_kp_enter(event):
    event.widget.event_generate('<Return>')
root.bind_class('Button', '<KP_Enter>', on_kp_enter)

def on_return(event):
    print('Return')

b = Button(root, text='Push me')
b.pack()
b.bind('<Return>', on_return)
root.mainloop()
